The Luminosity from Mass calculator approximates the luminosity of a star based on its mass.
INSTRUCTIONS: Choose the preferred units and enter the following.
- (M) This is the mass of the main sequence star. Note, the default units are in Solar Masses.
Luminosity: The calculator returns the luminosity of the star in Solar Luminosities, multiples of the luminosity of the of the Sun.
The Math / Science
There is a relationship between mass and luminosity for stars in the "hydrogen" burning phase of their life cycle (the so called "main sequence"). This formula estimates the luminosity of a main sequence star given its mass. The formula for luminosity from stellar mass is:
L = M3.5
where:
- L = Luminosity
- M = Mass of the Star
